监听端口5060

问题描述

我开发一个SIP客户端。为此，我一定要听传入SIP Server消息端口5060。为此，我的东西编码。 （我也参加节目管理员权限）

I developing an SIP client. For this I must listen to port 5060 for incoming SIP Server messages. For this I coded something. (Also I take admin rights in program.)

    WindowsPrincipal pricipal = new WindowsPrincipal(WindowsIdentity.GetCurrent());
    bool hasAdministrativeRight = pricipal.IsInRole(WindowsBuiltInRole.Administrator);
    if (hasAdministrativeRight == true)
    {
        TcpListener server;
        Int32 port = 5060;
        IPAddress localAddr = IPAddress.Parse("127.0.0.1");
        server = new TcpListener(localAddr, port);
        server.Start();
        Byte[] bytes = new Byte[256];
        String data = null;
        while (true)
        {
            Console.Write("Waiting for a connection... ");
            TcpClient client = server.AcceptTcpClient();
            Console.WriteLine("Connected!");
            data = null;
            NetworkStream stream = client.GetStream();
            int i;
            while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
            {
                data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
                Console.WriteLine("Received: {0}", data);
                data = data.ToUpper();

                byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);
                stream.Write(msg, 0, msg.Length);
                Console.WriteLine("Sent: {0}", data);
            }

            client.Close();
        }
    }

我得到SocketException：试图访问取得在某种程度上套接字由它的访问权限（本地错误代码：10013），禁止...

I get SocketException: "An attempt was made to access a socket in a way forbidden by its access permissions" (Native error code: 10013)...

你有这样的建议。

推荐答案

看来你正在运行两个应用程序，它们正试图
访问同一个插座上。

It seems that you were running two applications, and they are tryingto access the same socket.

什么：

WSAEACCES（10013）

• 翻译：权限被拒绝



• 说明：试图在
  在被禁止的方式来访问套接字由其接入
  的权限。例如，当一个广播地址
  用于SENDTO但广播权限不使用
  的setsockopt（SO_BROADCAST）设置发生此错误。

• Translation: Permission denied

• Description: An attempt was made to access a socket in a way that is forbidden by its access permissions. For example, this error occurs when a broadcast address is used for sendto but the broadcast permission is not set by using setsockopt(SO_BROADCAST).

的另一个可能原因的WSAEACCES
错误是，当绑定（Wsapiref_6vzm.asp）函数被调用（在
的Microsoft Windows NT 4。 0的Service Pack 4 [SP4]或更高版本），另一个
程序，服务或内核模式驱动程序绑定到同一个地址
独家访问。这种独占访问是$ B $的新特征B的Windows NT 4.0 SP4和更高版本，它是通过使用
SO_EXCLUSIVEADDRUSE选项实现。

Another possible reason for the WSAEACCES error is that when the bind (Wsapiref_6vzm.asp) function is called (in Microsoft Windows NT 4 .0 Service Pack 4 [SP4] or later), another program, service, or kernel mode driver is bound to the same address with exclusive access. Such exclusive access is a new feature of Windows NT 4.0 SP4 and later, and it is implemented by using the SO_EXCLUSIVEADDRUSE option.
